The Federal Trade Commission (FTC) has pointed the finger at Microsoft for today’s huge Xbox document leak that has seen a long list of revelations about unannounced hardware and games.
For me the biggest thing was motion controls in the future Xbox controller. To me that means motion controls in XInput, and a standardized motion control library on PC that's not reliant on Steam. Hopefully means multiplats will be more willing to implement them where they make sense, for people who like them.
